Safety instructions Copeland™ brand products semi-hermetic compressors are manufactured according to the latest European safety standards. Particular emphasis has been placed on the user’s safety. These compressors are intended for installation in systems according to the Machinery Directive MD 2006/42/EC. They may be put to service only if they have been installed in these systems according to instructions and conform to the corresponding provisions of legislation.

CAUTION Contact with POE! Material damage! POE lubricant must be handled carefully and the proper protective equipment (gloves, eye protection, etc.) must be used at all times. POE must not come into contact with any surface or material that it might damage, including without limitation, certain polymers, eg, PVC/CPVC and polycarbonate.
Product description Common information about Copeland Stream Digital™ semi-hermetic compressors These guidelines cover Copeland Stream Digital™ semi-hermetic compressors. The semi- hermetic reciprocating compressor family consists of different ranges. The Stream Digital series of 4M*D and 6M*D models ranges from 13 hp to 50 hp. Medium temperature Low temperature Nominal...
Nameplate information All important information for identification of the compressor is printed on the nameplate located below the compressor oil pump. The type of refrigerant used should be stamped on the nameplate by the installer. The year and month of production are shown as a part of the serial number (Jan. = A, Feb. = B, …...
one standard bank; one Digital modulated bank; one capacity-controlled bank (blocked suction std) only for 6M*D. NOTE: To upgrade 6M* compressors to 6M*D, Emerson Climate Technologies recommends to use the central cylinder bank. 2.6.2 Digital theory of operation Digital technology is now available on the 4M*D and 6M*D Stream compressors.

Due to the high life cycle requirements in a hot gas environment, a special valve has been developed. Due to reliability requirements, only Emerson solenoid valves may be used. All compressor warranties are null and void if the Emerson valve is not used. Solenoid coils will be sold separately for all Stream Digital compressors.
In the case of high-powered motors the breakaway starting currents become so large that they lead to disruptive voltage dips in the mains. The compressors that are subject to current limitation must therefore by all means be equipped with starting load reduction to guarantee perfect starting even when the voltages amount to less than approximately 85% of the voltage on the nameplate.
2.6.12 Multiple compressor application To ensure smooth and continuous modulation, ie, for optimum suction pressure control, the selection of the Stream Digital and Stream fixed-capacity compressors should be made according to the following rule: - F1 < D - F2 < D+F1 - F3 <...
Installation WARNING High pressure! Injury to skin and eyes possible! Be careful when opening connections on a pressurized item. Compressor handling 3.1.1 Delivery Please check whether the delivery is correct and complete. Any deficiency should be reported immediately in writing. Standard delivery: ...
In order to avoid refrigerant leaks or other damage the compressors should not be lifted by the service valves or other accessories. 3.1.4 Installation location Ensure the compressors are installed on a solid level base. 3.1.5 Mounting parts To minimize vibration and start/stop impulses flexible mounting should be used. For this purpose one set of spring mounting parts for each of the Stream models is delivered with each 4M*D and 6M*D compressor.
High-pressure side (HP): 28.0 bar(g) (up to S/N 14K46143M) 32.5 bar(g) (from S/N 14K46144M onwards) Low-pressure side (LP): 22.5 bar NOTE: The compressor operating range may be restricted for various reasons. Check the application range limitations in Copeland brand products Select software at www.emersonclimate.eu.
Electrical connection General recommendations The compressor terminal box has a wiring diagram on the inside of its cover. Before connecting the compressor, ensure the supply voltage, the phases and the frequency match the nameplate data. The knockouts have to be removed before the electrical glands can be installed. First make sure that the terminal box is closed with the terminal box cover.

Where there is a 5-wire cable connection between the electrical control panel and the compressor terminal box to the OPS module, the same wires can be applied to the OPS2 which will give the functions of an OPS1 module. To obtain use of all of the features of the OPS2 a 7-wire cable between the electrical control cabinet and the compressor terminal box should be used.
Crankcase heater IMPORTANT Oil dilution! Bearing malfunction! Turn the crankcase heater on 12 hours before starting the compressor. A crankcase heater is used to prevent refrigerant migrating into the shell during standstill periods. Heaters for 4M*D and 6M*D compressors are screwed into a sleeve (see Figure 22). The crankcase heater is available in 120V, 230V and 480V.
Starting up & operation WARNING Diesel effect! Compressor destruction! The mixture of air and oil at high temperature can lead to an explosion. Avoid operating with air. Leak test The suction shut-off valve and discharge shut-off valve on the compressor must remain closed during pressure testing to prevent air and moisture from entering the compressor.
Minimum run time Emerson Climate Technologies recommends a maximum of 10 starts per hour. The most critical consideration is the minimum run time required to return oil to the compressor after start-up. Pump-down In systems that require a compressor pump-down, special attention should be paid to the control logic for the Digital unloader coil.
Compressors supplied by Emerson Climate Technologies contain oil with low moisture content, and it may rise during the system assembling process. Therefore it is recommended that a properly sized filter-drier is installed in all POE systems.
Oil additives Although Emerson Climate Technologies cannot comment on any specific product, from our own testing and past experience, we do not recommend the use of any additives to reduce compressor bearing losses or for any other purpose. Furthermore, the long term chemical...
